Step 1: Determine your current electricity usage.

Ultimately, when you are looking to build your own Homemade Wind Generator you are looking to get off the grid completely. In order to completely get off the grid you will need to figure out what your currently hourly electrical usage is. One way to do this is to check with your electrical utility provider and get your total kW/hr usage. They will typically give it to you on a per hour basis (ie: 3 kW/hr) or as a total kW usage for the month. If they give you the total monthly kW usage of say 5000 kW, then you would need to divide that by the days in that month (ie: 5000/30 = 166 kW per day). You would then take this and divide it by 24 hours in a day and you have your general kW/hr on an hourly basis. With our example a usage of 5000kW a month would translate to roughly 6.9 kW/hr. The reason we want to break it down on an hourly basis is so we can make sure we have a strong enough generator for our wind turbine and we can determine what side blades we will need to use.

Step 2: Determine the size of your generator.

Your homemade wind generator will basically use the wind turbine blades to propel a generator. If your estimated kW/H usage was say 2 kW/h you will want to have a generator that can put out 3-4 kW/h. You always want to go with a generator that can produce 50-100% more power than you actually use, this way you can account for periods of low wind speeds. There are a couple ways you can obtain a generator.

One way is to build your own generator from scratch. I’m not going to go into lengthy detail on how to do this because there are websites that will go over it in more detail. Basically you need magnets to build your own generator. The more power you need the stronger magnets you will need to get. I recommend using Neodymium magnet’s with a pull force of at least 80lbs. The bigger the magnet the stronger the pull force will be and the more power it will produce. I recommend getting between 24 and 48 magnets in total to start crafting your generator. Then head on over to some sites that offer specific schematics on how to do it.

Another way to obtain a generator is to buy one. Local hardware stores sell gas/diesel generators all the way up to 10kW/h for a reasonable price. I have found many generators online ranging from $250-$600 for some of the bigger generators. You can take one of these and fabricate your own methods on how to build your own home made wind generator.

The final way to build your generator is to use car alternators. You can run multiple alternators in series to create additional power. This would most likely be the cheapest of the three methods because you can goto a junkyard and easily find 5-10 alternators to toy with for under $100.
